An automatic consistency check of the file systems will be performed, and unless this fails, the system will resume multi-user operations. .Ss Cold starts On a NeXT, the boot procedure uses the boot ROM to load a boot program over the network using BOOTP and TFTP. The .Pa /usr/mdec directory contains a network boot program which should be made available via .Xr tftp 1 . The network boot program will load .Pa netbsd from the NFS root as determined by the procedure described in .Xr diskless 8 . .Sh FILES .Bl -tag -width /usr/mdec/installboot -compact .It Pa /netbsd system code .It Pa /usr/mdec/boot boot program for NFS (diskless) boot .El .Sh SEE ALSO .Xr halt 8 , .Xr init 8 , .Xr rc 8 , .Xr reboot 8 , .Xr shutdown 8
